This allows plugins to add controls to nodes that already have some controls set by other plugin. Previously only the last plugin that sets the controls in the node would have its controls visible. That was because of NodeControls' Merge function that actually weren't merging data from two inputs, but rather returning data that was newer and discarding the older one.
